The use of the aeroplane, camouflage, hand grenades, rifle grenades and many other new and terrible forms of fighting made new systems necessary. In gas attacks alone there was enough to study to keep them busy many days in the week, and this branch was regarded as so important that drill after drill was held merely in teaching the boys the best and most rapid manner of adjusting the masks.
All this time Ned, Bob and Jerry were progressing. They were becoming stronger physically, and better able to stand hardship and exposure. They could take long marches, carrying heavy packs, without getting over tired, and they knew how to bind up wounds, how to apply first-aid dressings, and how to carry wounded comrades from the field.
Of course there was much that was unpleasant and hard. Many of their associates were different from those they had been used to, and they had to do what they were told—obey orders. No longer were they their own masters. They lived by rule and rote, and every minute of the day, save the recreation hours, had to be accounted for.
But they knew it was doing them good, and they knew it was in a good cause—the cause of humanity and world-betterment—and they did not complain, except perhaps in a good-natured way, and occasionally.
They had several more or less unpleasant encounters with Pug Kennedy and fellows of his ilk, but this was to be expected. Ned’s back completely healed and he was able to take his place in the hardest drills with his chums.
Somewhat to the surprise of the boys they found that rifle work was not rated as highly as they had expected it would be, for the reason, they were told, that it has been found that in the present war machine guns and artillery play such a big part.
Of course, for some time to come, the rifle will be the arm of the infantry soldier. But it is coming to be more and more an auxiliary, and not a direct means to an end. Hand grenades can do much damage in the enemy trenches, and are easier to carry than a rifle and many rounds of ammunition.
But of course there was rifle practice, and many a day the motor boys and their chums spent on the ranges, perfecting their aim. Every encouragement was offered them to become expert marksmen, and the three friends were not far from the front when the markings were made.
The spring had given place to summer, and the camp was not any too cool. But there were shower baths, and the officers were not over severe in drills when the weather was too hot. There was plenty of chance to cool off between drills.
Occasionally the boys would have short leaves of absence, on which they made trips to town and took in a show or two, getting in on “smileage” books, or reduced rate tickets.
